摘要
针对湘北某传统民居的被动式技术及其对室内热环境的影响,在夏季对室内外温度和围护结构表面温度进行了连续监测,并测试了过渡空间风速.结果表明,传统民居中气温按照室外、过渡空间、室内的顺序依次下降,热环境优于普通现代住宅,墙体互遮阳使得被遮阳的墙面温度明显降低,南外墙内外表面温度衰减和延迟现象明显,过渡空间通风以水平通风为主且风速稳定.结合建筑设计和构造特点,可认为高密度规划、过渡空间的设置、重质墙体的应用、适当的窗墙比和开口遮阳等可有效改善夏季室内热环境.
Long-term field measurements of the indoor and outdoor temperatures, the surface temperature of building envelop and air speed were used to analyze the thermal environment, influenced by the applied passive technologies, in the typical Chinese traditional residential building in the north of Hunan Province in summer. The results showed that the air temperature of the traditional residential building outdoors, transitional spaces and indoors decreased and were lower than that of the modern house; the attenuation and time lag between the outside and inside surface temperature of the southern wall were obvious,and the wall surface temperature with the shading devices was lower than that of the wail without shading; in the transitional spaces, the wind direction was along the south-north axis and the speed was stable. Together with the analysis of building design and construction, some valuable conclusions were summarized: high-density housing planning encouraged passive cooling; proper window-wall ratio and good shading design for openings improved the indoor thermal environment; the solid wall with a large thickness showed good thermal insulation in summer; the shading and natural ventilation effects of transitional spaces were useful for the improvement of the indoor thermal environment.
